Explain four thermodynamic potentials
WebApr 12, 2024 · 5: Thermodynamic Potentials. This chapter begins with a discussion of mathematical properties of the total differential of a dependent variable. Three extensive state functions with dimensions of energy are introduced: enthalpy, Helmholtz energy, and Gibbs energy. These functions, together with internal energy, are called thermodynamic … WebThe fundamental thermodynamic equation for Gibbs Energy follows directly from its definition 22.5.3 and the fundamental equation for enthalpy 22.5.2: dG = dH − d(TS) = dH − TdS − SdT. Since. dH = TdS + VdP. dG = TdS + VdP − TdS − SdT. dG = VdP − SdT. The above equation is the fundamental equation for G.

A thermodynamic potential (or more accurately, a thermodynamic potential energy) is a scalar quantity used to represent the thermodynamic state of a system. Just as in mechanics, where potential energy is defined as capacity to do work, similarly different potentials have different meanings. The concept of … See more Five common thermodynamic potentials are: where T = temperature, S = entropy, p = pressure, V = volume. Ni is the number of particles of type i in the system and μi is the See more For each thermodynamic potential, there are thermodynamic variables that need to be held constant to specify the potential value at a thermodynamical equilibrium state, such as independent variables for a mathematical function. These variables are termed the … See more Again, define xi and yi to be conjugate pairs, and the yi to be the natural variables of some potential Φ.
